Inference tools for RVC

RVC INFER PY

rvc_inferpy is a Python library designed for audio inference using RVC (Retrieval-based Voice Conversion). It provides a straightforward interface to process audio files with various configurable parameters.

Installation

Install the package using pip:

pip install rvc-inferpy

Usage

Here's a simple example demonstrating how to use the library:

from rvc_inferpy import infer_audio

inferred_audio = infer_audio(
    MODEL_NAME="model_name_here",       # Name or path to the RVC model
    SOUND_PATH="path_to_audio.wav",    # Path to the input audio file
    F0_CHANGE=0,                       # Change in fundamental frequency
    F0_METHOD="crepe",                 # F0 extraction method ("crepe", "dio", etc.)
    MIN_PITCH=50,                      # Minimum pitch value
    MAX_PITCH=800,                     # Maximum pitch value
    CREPE_HOP_LENGTH=128,              # Hop length for Crepe
    INDEX_RATE=1.0,                    # Index rate for model inference
    FILTER_RADIUS=3,                   # Radius for smoothing filters
    RMS_MIX_RATE=0.75,                 # Mixing rate for RMS
    PROTECT=0.33,                      # Protect level to prevent overfitting
    SPLIT_INFER=True,                  # Whether to split audio for inference
    MIN_SILENCE=0.5,                   # Minimum silence duration for splitting
    SILENCE_THRESHOLD=-40,             # Silence threshold in dB
    SEEK_STEP=10,                      # Seek step in milliseconds
    KEEP_SILENCE=0.1,                  # Keep silence duration in seconds
    FORMANT_SHIFT=0.0,                 # Amount of formant shifting
    QUEFRENCY=0.0,                     # Cepstrum quefrency adjustment
    TIMBRE=1.0,                        # Timbre preservation level
    F0_AUTOTUNE=False,                 # Enable or disable F0 autotuning
    OUTPUT_FORMAT="wav"                # Desired output format (e.g., "wav", "mp3")
)

Usage with cli

you can also use with cli by:

rvc-infer -h

Parameters

• MODEL_NAME: Name or path of the RVC model to use.
• SOUND_PATH: Path to the input audio file to be processed.
• F0_CHANGE: Adjusts the fundamental frequency (F0) of the audio.
• F0_METHOD: Method for extracting F0 (e.g., "crepe", "dio").
• MIN_PITCH / MAX_PITCH: Minimum and maximum pitch values for processing.
• CREPE_HOP_LENGTH: Hop length parameter for the Crepe method.
• INDEX_RATE: Determines the index rate for the inference model.
• FILTER_RADIUS: Radius used for smoothing filters.
• RMS_MIX_RATE: Mix rate for RMS adjustments.
• PROTECT: Protects specific audio characteristics from overfitting.
• SPLIT_INFER: Splits the audio for inference if set to True.
• MIN_SILENCE: Minimum silence duration for splitting audio (in seconds).
• SILENCE_THRESHOLD: Threshold to detect silence (in decibels).
• SEEK_STEP: Seek step in milliseconds during splitting.
• KEEP_SILENCE: Duration of silence to retain after processing.
• FORMANT_SHIFT: Amount of formant shifting applied.
• QUEFRENCY: Adjusts the quefrency in the cepstrum domain.
• TIMBRE: Controls timbre preservation during processing.
• F0_AUTOTUNE: Enables or disables F0 autotuning.
• OUTPUT_FORMAT: Specifies the output file format (e.g., "wav", "mp3").

Output

The function returns an audio object with the processed audio based on the provided parameters.

Information

you must upload your models in models/model_name folder
